High Pitch Noise Coming From Pinebook Pro

[this_machine]

Same problem with recent batch here. Max/min screen brightness kills the noise, capslock changes the tone, it actually hurts my ears.

Is this something that can be fixed with a firmware flash or do we have to apply epoxy somewhere?

I know that we can report problems and all that, but at the end of the day, I need actual fixes. If a part needs replacing, I'll have to order it soon before classes start. As it stands right now, I cannot use this at the library or in-class because the noise is painfully audible. I'd even say it's unusable without a headset when I'm just using it for around-the-house computing.
